除了这种交叉加锁，

void Foo()
{
    std::lock_guard guard1{m_mutex1};
    std::lock_guard guard2{m_mutex2};
    ...
}

void Bar()
{
    std::lock_guard guard2{m_mutex2};
    std::lock_guard guard1{m_mutex1};
    ...
}

看到好多这种死锁：

int ThreadProc() {
    ...
    std::lock_guard guard{m_mutex};
    ...
}

void StopThread()
{
    std::lock_guard guard{m_mutex};

    if (m_thread != nullptr)
    {
        m_thread->join();
        delete m_thread;
        m_thread = nullptr;
    }
}
